First post to the site, hope I'm not alone in my issue. We have ~150 users, half of which are Mac users. About once a month we have a Mac user who was able to connect to their VPN client but suddenly stops working. Message received after inputting credentials:

"Your session terminated unexpectedly. A software error caused the tunneling service to terminate. See the log viewer for more information." - nc.mac.app.1203

Generally we have them uninstall the application and delete all extra files from file system, hit our url from Safari, re-download the Network Connect application: currently we are at 7.1.0 (19243)

We've found this is related to user profiles. I can login to another user profile on the system and connecting to VPN works. We then migrate the user to a new profile on the Mac which is a pain but ends up solving the problem, that or migrating them to another system. Generally nothing is changed on the system in terms of updates or new programs.

Juniper suggests only: nc.mac.app.1203System Log Message Your session terminated unexpectedly.Cause A software error caused the Network Connect tunneling service to terminate. This may have been the result of a non-zero exit code—usually indicative of a software crash. (See the Log Viewer for more information.)Action Try signing in to the secure gateway again. If you still cannot establish a connection to the secure gateway, contact your system administrator

If anybody's seen this let me know, or if you have any ideas. Thanks -Ben

have iMac 3.1GHz running 10.6.8. Same here, it no longer works. I too have tried reinstalling, repairing permissions, ... still not working. I was hoping to find a solution before I do an archive install. I don't understand the errors in the log, but in case someone else does, I've attached them. Thanks

In my case, the error (nc.mac.app.1203) always occurs from a given machine (even after re-imaging it !), while the user can get things to work if they sit down at a different machine.The OS is Mac OS X Lion 10.7.3 (11D50).The Network Connect version is 7.1.0 (19757).

Enabling a different network interface (wireless vs. wired ethernet) does not make any difference in the observed symptoms.Geting a new and different IP via DHCP does not help.Other machines in the same office with the same hardware and OS are still working.

Hi, We are now on version 7.3.3. I had it working perfectly until I had to reinstall OSX after HD crash. I got error nc.mac.app.1203.I still manage to connect using IE on parallel desktop.I did all steps mentioned above without success. All browsers give the same issue. Any update on how to solve this issue?Cheers

I did the install via the NetworkConnect menu, and that did not work. I had to also do a find from the root of the filesystem on both ncproxyd and juniper, and delete these too. Only then did my re-install work such that the problem went away.

So it appears that some data file within the turds left by the client became corrupt. It would be nice if the un-install really did a full un-install, but perhaps there are reasons for that, like maybe some definitions or logs might be valuable. However, one would think though that this could be an option on the un-install - more of a deep uninstall.

Also of interest is that while the problem was present, if I ran "netstat -r" from the command line, it produced the correct output but then crashed with an "Abort 6". This only happened with the -r option, and only when run as my own user id - running as root did not have the issue. So this makes me think that there was something in the Library cache for my user that was causing problems for netstat.
